HEX to OKLCH: #FFEFD5

Also known as: CSS papayawhip

#FFEFD5 → oklch(0.958 0.038 80.0)

Values are shown at full precision, so converting back gives exactly #ffefd5. The rounded form is what you normally paste into CSS.

Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. sRGB → linear

R: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)
G: 239/255 = 0.93725 → 0.863157  (((x + 0.055) / 1.055)^2.4)
B: 213/255 = 0.83529 → 0.665387  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.909392
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.870915
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.750650

3. cube root

l′ = ∛0.909392 = 0.968836
m′ = ∛0.870915 = 0.954975
s′ = ∛0.750650 = 0.908823

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.95808
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.00662
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.03768

5. Oklab → OKLCH

C = √(a² + b²) = 0.03826
H = atan2(b, a) = 80.032°
L = 0.95808

6. OKLCH

oklch(0.95808 0.03826 80.032)
rounded: oklch(0.958 0.038 80.0)
